Interaction second virial coefficients from a recent H2–CO potential energy surface

Abstract
Interaction second virial coefficients for mixtures of hydrogen and CO are computed from a recent rigid rotor potential energy surface [J. Chem. Phys. 108, 3554 (1998)]. The calculations include the most important quantum corrections. A comparison with experimental data indicates that the attractive well of the ab initio surface is too deep by 4%–9%.
